(Published on 21. December 2012, 00:00 by Eisbär)
City construction Sudoku
Place the digits from 1 to 9 in every row, column and 3x3-block.
Place all buildings in the grid. Buildings may be rotated and mirrored. They may not touch each other, not even diagonally. All unused cells form a single, closed loop. None of the buildings may be placed on a digit that is already given in the grid.
This puzzle is inpired by Richard’s City construction puzzle.
Solution code: Column 9, followed by the number of knicks in the loop, row by row, top to bottom.

Sicherlich ist dieses schöne Rätsel leicht zu lösen, aber über die Spanne, was inzwischen alles als sehr leicht durchgeht, wundere ich mich schon. Auch bei manch anderen Rätseln fiel mir auf, dass die Qualitäten der Rater inzwischen so ausgeprägt sind, dass Riesenunterschiede zwischen echten Einsteigerrätseln und anderen Einsternern bestehen.
